[Value of blood creatinine in children].

Non-standardized values of serum creatinine are studied in 205 children aged 3 months to 12 years. Data are collected from paediatric patients hospitalised for mild illness without previous renal impairment; these values are quite comparable to those related in the literature based or standardised methods. The normal age-dependent serum creatinine values (mean +/- 2 SD) are shown in a graphic curve, which confirms that serum creatinine increases with age and that it is a faithful parameter to estimate the glomerular filtration rate in children.
